we have two pet hens. They are just gettin gover pox. Now one0out of the blue-doesn't seem well. She looks sort of off. She is not eating her favorites. She nibbled. She also ate grit for the first time I noticed. BUT our grit is very small with pieces of shell. She looks like she is trying to poo. I saw one small slimy ans white poo. HELP. I am more worried that with pox. BTW I see no signs of anything on her face like wet pox. SHE LOOKS LIKE SHE KEEPS TRYING TO POO. HER BUTT KEEPS MOVING LIKE THAT OR MOVING LIKE SHE IS BREATHING FROM THERE. I SEE A FEW TINY POOPS AND SOME ON HER FEATHER. This am I looked at her anus and it was clean.
